LEVER FOR Loolvls.

SPECIFICATION forming part of Letters Patent No. 414,852,dated November12, 1889.

VApplication filed August 27, 1889.' Serial No. 322,071. (No model.)

To all whom, t may concern,.-

Be it known that we, HORACE IVYMAN and ALBERT A. GORDON, both ofWorcester, county of Vorcester, State of Massachusetts,

have invented an Improvement in Levers for Looms, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

The levers used in connection with the shedding and shuttle-boxmechanisms in fancy. looms are commonly made with notched ends, for theattachment thereto of cording extended to the harnessframes and to partsI 5 of the shuttle-box mechanism, and these levers are made bothstraight and angular. These levers, commonly made of cast metal, are subj ected to very considerable strain, and in Y rapid movement arefrequently broken in 2o the line of one of the notches, the latterweakening the levers. ficulty, we have provided the cast-metal leverswith wrought-metal or steel notched ends, the said ends being firmlyconnected to the body of the lever by casting' or welding, or

in other strong manner.

Our invent-ion consists, essentially, in a loom-lever composed of acast-metal body and notched end pieces secured thereto, as will 3c bedescribed.

Figure l, in side elevation, shows one form of straight lever and Fig. 2one form of elbowlever with our improvement added.

The lever shown in Fig. l, it being an up-l 3 5 rightlever, is composed,essentially, of a castmetal body a and independent wrought-metal orsteel ends b l) secured firmly thereto. The lever a has pivoted to it anotched jack c. The elbow-lever shown in Fig. 2 is also com- To overcomethis difposedof cast-metal body, as d, it having con- 4o nected to itthe independent notched ends b b, composed of wrought or sheet metal orsteel. In the formation of the said loom the independent ends b l), ofcast malleable iron or steel, or out or punched from sheet or wroughtmetal or steel, it being tougher and stronger than cast iron, may belaid into the usual mold and the cast metal be poured into the mold soas to lap over upon the ends of the said end pieces, the cast metalbeingmade 5o to adhere to the independent end pieces or to` be weldedthereto, as common in uniting two metals by casting.

In Fig. l the line of junction is shown at d; but the line of junctionmay be angular, and so also the end pieces may be joined to the body inother ways than that describeddas, for instance, by electrically weldingone part to the other.

The wrought-iron or steel end pieces can- 6o not be broken off bystrains in weaving, and a lever improved by the addition to it of thesaid end pieces is much more desirable than when the notches are in acast-metal part of the lever.

We claim- 'A loom-lever composed of a cast-metal body and notched endpieces of a tougher metal, substantially as described.

In testimony whereof We have signed our 7c names to this specificationin the presence of two subscribing witnesses.
